(S/E) From the town hall car park, turn left to go up the D41 towards Grosne, leaving Rue de l'Ardennaise on your left, then Impasse des Prés Charmilles on your right. At the next roundabout, turn right without leaving the D41. Caution: traffic.
(1) At the village exit, turn left onto Rue des Chaumières, turn right with the street and continue to a crossroads. Turn left and continue straight ahead on the farm track which turns right, left and then right again, running alongside a copse and ponds.
(2) At the entrance to Grosne, turn left and the route descends between two ponds. At the next crossroads (elevation 368), turn right and then right again (elevation 363) onto the path that returns to Grosne and leads to the D41. Continue for about 50 metres to the left.
(3) Turn right to go up Rue de la Fontaine, which quickly joins Rue du Général de Gaulle (D13). Continue to the right and follow the D13 to Vellescot. At the central crossroads, turn left onto the D3, then leave the D11 on your left. Caution: traffic.

(5) At the next crossroads, turn right. At a pond, the path veers to the right (south) and crosses a wood for over a kilometre before reaching the dyke of the Étang du Poirier Lourd.
(6) Walk along the right-hand side of the pond and join the D13.
(7) Cross it carefully and go down the steps opposite to reach the pond. Turn left and go around the pond. Turn right when you reach the forest and walk along the other side of the pond. Cross the footbridge and continue along the path in the forest. Follow the markings carefully and leave a path on your right. The path runs along a narrow strip of forest between two fields and further on joins a main path.

(9) Turn right to return to the first houses in Boron.
